POLYHYDROXY ESTERS CONTAINING CARBOXYL END GROUPS AND THEIR USE

摘要

Curable compositions of matter containing (a) an epoxy resin and (b) a polyhydroxy ester containing carboxyl end groups which is obtainable by reaction of a diepoxide with a dicarboxylic acid in the presence of a basic catalyst, the amounts of the diepoxide and dicarboxylic acid being chosen so that 1.04 to 1.4 carboxyl groups of the dicarboxylic acid are present per epoxide group of the diepoxide, are suitable for the production of crosslinked products, in particular as adhesives or for the production of flexible coatings.
